VCP6-DTM exam – Section 2.2


In the attachment, you will find VCP6-DTM exam Objective 2.1 and 2.2 besides the complete Section 1.

Section 2 contains a lot of material, for that reason I’ve decided to split up this section.

I hope you like this guide, and welcome your comments.

View 6.2.1. Upgrade, two caveats


Recently, I was performing an upgrade from View version 6.0.1 to 6.2.1. On other occasions upgrades from version 6.0.1 to 6.2.0 did not cause serious issues. View 6.2.1 is said to be a “maintenance” release, so I did not expect much problems.

The update of the standalone View Composer, the Connection Server and the Security Server went smoothly. After this stage it is a good practice to test the functionality of the View Composer and the Connection Server and Security Server. Setting up a connection from a Windows Horizon Client, went well, but after selecting a desktop pool, the following error was received “Unable to connect to desktop: There is no available gateway for the display protocol. Try again etc…”

The Connection Server log files showed the following error message: “ERROR (0894-1510) <ajp-nio-8009-exec-1> [DesktopsHandler] (SESSION:3580_***_7533) No co-management availability for protocol PCOIP””.

Wots … Uh the Driver?


A modern server is besides our favorite ESXi hypervisor loaded with all kinds of additional software, like BIOS, and firmware and drivers for items like; Baseboard management , Remote support interfaces, Storage controllers, NICs, Power Supplies, to name a few.
If trouble arises and you must contact your hardware vendor or VMware support, in many situations you are kindly requested to install the latest updates, firmware versions and drivers.

Some vendors provide ISO images or repositories containing the actual updates, you may run the update process and voilà, ready and done.
If you want to stay in control and want some more insight in this subject, please read on.

It comes down to these four questions:

  • What hardware is in the server?
  • How to determine the current firmware and or driver?
  • Which driver and or firmware do I need?
  • How do I upgrade drivers and firmware?

Implementing CA signed SSL certificates with vSphere 5.x – Part 6 – Horizon View


In a VMware Horizon for View environment (VMware’s VDI solution), View Connection servers are an important client facing component. A View Connection Server acts as a broker for client connections and for that reason VMware highly recommends that you replace the default SSL certificates which are generated during the installation of the Connection servers.

To help you with this job, VMware has a lot of useful documentation available, like:

For each View Connection server you should perform these basic tasks for setting up SSL Certificates:

  1. Generate a Certificate Signing Request
  2. Request a signed Certificate from a CA
  3. Import the signed Certificate
  4. Set up the imported Certificate for a View server
  5. Import Certificates on other View Servers

In the next sections I will show you the steps and some tips to step over some of the caveats.

VCP6-DTM exam – Section 1


In my previous post I discussed the changes between the VCP6-DT exam and the new VCP6-DTM exam. So, it is not surprising that at this time, my focus is on VMware’s desktop and mobility solutions, in other words: Horizon 6, AirWatch etc.

To gain knowledge and experience, I tend to do the following:

  • Read books, whitepapers, blogs and documentation.
  • Watch and study Video trainings e.g. Pluralsight.
  • Build labs and practice a lot.
  • Work on real-world projects.
  • Work towards a certification

I strongly believe in the value of certifications, but in my opinion, one should only take an exam after a solid preparation.
VMware’s Exam Blueprints help you to determine which objectives are covered in an exam or not. Without these it would not always that clear and the number of VMware products is huge these days!

Exam Blueprints help me to review the objectives, so for me filling in the objectives makes sense and helps me in my preparations.

In 2012, I first published my study notes for the VCAP5-DCA exam (version VDCA510) as a series of blogpost. Last year I published an updated version for the VDCA550 exam.

Because converting a Word document to WordPress takes a considerable amount of time, from the VDCA550 exam, I published the various sections as downloadable documents.

In this post, you will find the first section of the new VCP6-DTM exam. I hope you will enjoy it. I welcome your comments.

Download new VCP6-DTM exam – Section 1




Some time ago I started my preparations for the VMware Certified Professional 6 – Desktop (VCP6-DT) certification. Last week I noticed that the VCP6-DT exam and certification will be retired as soon as November 30, 2015.

2015-08-24-01Figure 1

This year VMware started making major changes in their Certification Roadmap, like abandoning the Advanced Professional level and introducing the Implementation level. The number of new Version 6 exams is still growing. An overview of the available certifications can be found here.

For an overview of retired exams and certifications can be found here.

The VCP6-DT and the VCP5-DT certifications will be replaced by the new VCP6-DTM certification. The exam details and objectives can be found here.

Another difference between Version 5 and Version 6 certification; VMware does no longer publish a downloadable Exam Blueprint but only an online version. A “Last Updated” section has been added. I also hope version control will also be added in the future.

I have converted the exam topics, dated 27 July 2015 in a downloadable document. Links to the documentation have been added.

You still got time


As you may have heard, on 30 June 2015, the last minute of the day 23:59 UTC will last 61 seconds instead of 60 seconds. The reason for this leap second is to sync time with the rotation of our Earth. The previous leap second was added in 2012, websites like LinkedIn, Mozilla and Reddit went down due to this leap second.

20150628_01Figure 1

Because a progressive number of computer systems rely on time synchronization, this means extra work for System Administrators (that will take much longer than 1 second). On the other hand there is also a lot of discussion; are leap seconds really useful in a world that relies on computer systems?

That brought me to the question; “Are VMware products affected and what can we do to prevent misery?”
